I've been
doing that for some time, and probably have about 50 or so stockpiled.
 BUT, it may be just a waste of time. I put up 20 100-450 MB IDE and SCSI HDs on
 VCM, then Ebay, and back on VCM more out of curiosity to see if there was a
 demand. Right now, there doesn't seem to be. 
 Eventually, there might be.  IDE drives from 300-500 (but under the
 540MB BIOS limit of early 386s) are still somewhat sought after.  I
 wouldn't expect more than $5 for each drive though.
